Glycolysis

Question 1

What is the molecular formula for glucose?

Answer 1

C6H12O6

Glucose is a simple sugar and an important carbohydrate in biology.

Question 2

What happens to ATP during the conversion of glucose to glucose-6-phosphate?

Answer 2

ATP to ADP

This process involves the phosphorylation of glucose.

Question 3

What is the structure of glucose-6-phosphate?

Answer 3

6C

This is a phosphorylated form of glucose.

Question 4

What is the next step after glucose-6-phosphate in glycolysis?

Answer 4

Fructose-6-phosphate

This is formed from glucose-6-phosphate through isomerization.

Question 5

What is the role of NAD in glycolysis?

Answer 5

NAD* - NADH+H*

NAD is reduced to NADH during glycolysis.

Question 6

What is produced from fructose-1,6-bisphosphate?

Answer 6

(Phosphoglyceraldehyde (3C) and Dihydroxy acetone phosphate (3C))

These are the two triose phosphates formed.

Question 7

What is the outcome of converting 1,3-bisphosphoglyceric acid?

Answer 7

2x (3-phosphoglyceric acid) (3C)

This conversion involves the production of ATP.

Question 8

Fill in the blank: The conversion of 2x 2-phosphoglycerate produces _______.

Answer 8

H2O and 2 x phosphoenolpyruvate

This step involves dehydration.

Question 9

What is formed from phosphoenolpyruvate?

Answer 9

2 x Pyruvic acid (3C)

This is the final product of glycolysis.

Question 10

What is the relationship between ATP and ADP in glycolysis?

Answer 10

ATP is generated from ADP

This occurs during substrate-level phosphorylation.
